Definitions

  • the invention relates to a micro-negative pressure system in the field of medical device research, in particular to an intelligent humidity-controlled temperature-controlled spray burn treatment system.
  • the traditional treatment method for severe burns and burns is not only extremely painful for the patient, but also faces problems such as delayed wound healing, residual scars after the healing, and even endangering the patient's life!
  • How to improve the clinical treatment methods and treatment plans according to the pathophysiological characteristics of patients with burn wounds is very important, and the social and economic benefits are huge.
  • I degree burns also known as erythema burns
  • erythema burns only a part of the epidermis, but the germinal layer is healthy, so the proliferation and regeneration ability is active, often healed within 3 to 5 days, leaving no scars.
  • shallow second degree burns refers to the injury of the entire epidermis and part of the papillary layer. Due to the partial damage of the germinal layer, the regeneration of the epithelium depends on the residual germinal layer and skin attachments, such as epithelial proliferation of sweat glands and hair follicles. If there is no secondary infection, it usually heals in about 1 to 2 weeks, and no scars are left.
  • Deep second degree burn refers to the deep burn and below the dermal papilla layer, but still remains part of the dermis and skin attachment.
  • the healing depends on the epithelium of the skin attachment, especially the proliferation of epidermal progenitor cells in the hair follicle protrusion. If there is no infection, it usually takes 3 to 4 weeks to heal itself, often with scars. The clinical variation is more, the shallow is close to the shallow II degree, and the deep is the critical III degree.
  • III degree burn also known as eschar burn. Generally refers to the burn of the whole skin, the epidermis, dermis and skin attachments are all destroyed, and the wound repair depends on the surgical skin graft or flap repair.
  • Grade IV burn refers to deep burns and muscles, bones and even internal organs. Wound repair depends on surgical skin graft or flap repair. In severe cases, amputation is required.
  • the local tissue damage caused by burns and burns is divided into three layers: coagulation necrosis zone, stasis zone, and congestion zone.

  • the obvious edema of small area burn is limited to the burn site, and the systemic reaction is not obvious. For severe burns, edema can occur in the tissues adjacent to the burn; extremely severe burns and edema can be found in the whole body including visceral tissues.
  • I degree burns generally do not require treatment, and the degree of systemic dysfunction can occur when the burn area of adults with burns of more than 2 degrees is more than 15%. Namely: 1 oozing shock stage; 2 liquefaction poisoning stage; 3 wound repair healing stage; 4 functional rehabilitation stage.
  • necrotic tissue layer In the liquefaction and repair healing stage of necrotic tissue in burn wounds, the necrotic tissue layer not only forms a standing position, but also leads to the growth of residual dermis and skin attachment neoplastic epithelium and skin island, and the absorption of necrotic tissue dissolved toxin may cause systemic poisoning of the wounded. Clinically, the use of cutting and cutting surgery to remove necrotic tissue sites. However, because the necrotic tissue layer and the normal tissue boundary are unclear, normal tissue damage will inevitably occur during the operation. Traditional biomaterials and burns and scalds do not solve the above problems.
  • the local repair process of burn wounds is that the residual dermis or skin attachment first forms “new epithelial cells” and “peel islands".
  • the link between the "new epithelial cells” and the “peel island” cells is gradually formed, and the links between the cells are loose at the beginning and are easy to fall off.
  • various clinical treatment methods have the phenomenon that the neoplastic epithelial cells and the "peel island” which are gradually germinated in the dermis layer and the residual part of the exudate and the necrotic tissue are unclear.
  • Traditional clinical treatment requires repeated dressing changes and debridement. Debridement or dressing change Because of the force of the doctor's operation, even a slight movement such as wiping with a cotton ball may cause a certain degree of damage to the newborn cells, or even be removed and fall off, resulting in delayed healing of the wound surface.

Système intelligent de traitement par vaporisation de brûlures et échaudures à commande de température et d'humidité comprenant un corps principal de commande intelligente (1) de la température et de l'humidité, une pompe à vide (2), un capteur de mesure de l'humidité, un flacon de stockage (3) de liquide, un cathéter d'aspiration (4), une couche de drainage et de pansement (5), une membrane adhésive (6) à usage médical, un vaporisateur (8), un dispositif de commande de la température (80), un premier capteur de mesure de la température et un cathéter de vaporisation (9). Ce système est caractérisé en ce qu'une extrémité du cathéter d'aspiration (4) est en communication directe ou indirecte avec un mécanisme tridimensionnel d'interfonctionnement, en ce que le capteur de mesure de la température pénètre directement ou non la couche de drainage et de pansement (5), et en ce que le cathéter de vaporisation (9) est en communication directe ou indirecte avec le mécanisme tridimensionnel d'interfonctionnement, le premier capteur de mesure de la température étant en communication directe ou non avec la couche de drainage et de pansement (5). Le capteur de mesure de l'humidité et le premier capteur de mesure de la température, disposés sur le corps principal de commande intelligente (1) de la température et de l'humidité, renvoient en temps réel des informations concernant la température et l'humidité de la plaie selon la température de la plaie et la plage de commande de la température, lequel corps principal de commande intelligente (1) régule le jet du vaporisateur (8) pour s'adapter à la température ou aux différents états de fonctionnement d'aspiration de la pompe à vide (2) de telle sorte que la brûlure ou échaudure guérisse dans les meilleures conditions.
